A method for controlling a vehicle according to an embodiment of the present application will be described below.

Referring to fig. 1, fig. 1 is a first flowchart illustrating a control method of a vehicle according to an embodiment of the present disclosure. The control method of the vehicle shown in fig. 1 may be performed by a first subscriber identity card SIM built in the first terminal.

As shown in fig. 1, the control method of a vehicle may include the steps of:

step 101, after establishing a Near Field Communication (NFC) connection between a first SIM and a vehicle, sending a verification request to the vehicle;

step 102, receiving random information sent by a vehicle in response to an authentication request;

103, signing the random information based on the first private key, and sending the signature information to the vehicle;

104, receiving feedback information sent by the vehicle after the signature information is verified based on the first public key, wherein the feedback information is used for indicating that the unlocking of the vehicle is successful; the first private key and the first public key in the first vehicle key data are corresponding key pairs.

As can be seen from the foregoing steps 101 to 104, the first vehicle key data is stored in the first SIM built in the first terminal, but not stored elsewhere in the first terminal, for example, in the APP of the first terminal, so that the security of the first vehicle key data is improved; in addition, the first SIM can directly perform data interaction with the vehicle through NFC, namely the random information sent by the vehicle can be signed through a first private key in the first vehicle key data, so that the vehicle can inform the first SIM of successful unlocking after the vehicle verifies the random information through the first public key; because first SIM self has the NFC function, need not to consider whether operating system and the vehicle of terminal match, consequently, only need the vehicle also to have the NFC function and can realize NFC. Therefore, through this application, solved among the prior art digital car key security lower, and to the higher problem of limitation at terminal.

It should be noted that, in the embodiment, the first SIM and the second SIM in the present application may be USIMs (Universal Subscriber Identity modules, Universal Subscriber Identity cards) in a specific embodiment. The terminal in the embodiment of the application can be a mobile phone, a smart watch, a tablet computer and the like.

In an optional implementation manner of the embodiment of the present application, before establishing the NFC connection with the vehicle, the method of the embodiment of the present application may further include:

step 11, after the first terminal applies for the car key service to the background server, establishing the Bluetooth connection with the first terminal;

step 12, receiving data of a target application program sent by a first terminal;

step 13, installing a target application program locally based on the data, and generating first vehicle key data based on the target application program;

and step 14, pushing the first public key to the background server through the first terminal, wherein the first public key is sent to the vehicle by the background server.

It can be known from the foregoing steps 11 to 14 that, before the first SIM controls the vehicle through the first vehicle key data, the first SIM needs to apply for a vehicle key service to be started first, and a bluetooth connection between the first SIM and the first terminal needs to be established in a vehicle key service starting process, so that the first SIM and the first terminal can implement data communication, and thus, data of a target application program sent to the first terminal by the background server may be sent to the first SIM through the bluetooth connection, so that the first SIM can deploy the target application program generating the first vehicle key data to the first SIM, and thus, an APP does not need to be deployed in the terminal to generate the first vehicle key data, and the first vehicle key data can be generated in the first SIM, thereby improving security of the vehicle key data. In addition, the first SIM needs to send the first public key to the vehicle through the first terminal and the backend server, so as to perform subsequent unlocking control on the vehicle.

In another optional implementation of the embodiment of the present application, the method of the embodiment of the present application may further include:

step 21, after a second SIM built in a second terminal generates second vehicle key data based on a link shared by the first terminal, obtaining a request for applying an authorization certificate sent by the second SIM through a background server, wherein the second vehicle key data includes a second private key and a second public key which are a key pair; the request for applying the authorization certificate carries a second public key;

step 22, under the condition of establishing Bluetooth connection with the first terminal, receiving a notice which is sent by the first terminal and used for generating an authorization certificate; the notification for generating the authorization certificate carries a second public key;

step 23, generating an authorization credential in response to the notification for generating the authorization credential, wherein the authorization credential is the authorization credential signed by the first SIM using the first private key; the signature certificate carries a second public key;

step 24, sending the authorization credential to the second SIM.

Through the above steps 21 to 24, after the second SIM built in the second terminal generates the second vehicle key data based on the link shared by the first terminal, the second SIM may send the second public key to the background server, further, the background server sends a notification for generating the authorization credential to the first SIM, where the notification carries the second public key, and the first SIM responds to the notification, and signs the authority information and the second public key with the first private key to obtain the authorization credential, after the second SIM receives the authorization credential, and after the second SIM establishes the NFC connection with the vehicle, the vehicle may verify the authorization credential with the first public key, since the authorization credential is signed with the first private key, the verification is enabled, and at this time, the vehicle holds the second public key, so that the subsequent unlocking process of the second SIM to the vehicle is consistent with the result process of the first SIM, and verifying the second public key and the second public key to realize unlocking. That is to say, in this application embodiment, the first terminal can share the car key business to the second terminal, then made things convenient for other people to use the vehicle, avoided the inconvenience of entity car key sharing process.

The above is to explain the embodiments of the present application from the first SIM of the first terminal, and the present application will be explained from the perspective of the first terminal.

Referring to fig. 2, fig. 2 is a second flowchart illustrating a control method of a vehicle according to an embodiment of the present application. The control method of the vehicle shown in fig. 2 is executed by the first terminal.

As shown in fig. 2, the control method of the vehicle may include the steps of:

step 201, sending a request for applying for a car key service to a background server;

step 202, receiving data of a target application program sent by a background server under the condition that the background server passes the identity authentication of the first terminal;

step 203, under the condition of establishing Bluetooth connection with a first SIM built in a first terminal, sending data of a target application program to the first SIM;

step 204, after the target application program is installed on the first SIM, receiving a first public key in first vehicle key data fed back by the first SIM, wherein the first vehicle key data further comprises a first public key and a first private key which are mutually key pairs;

step 205, the first public key is sent to the vehicle through the background server.

Through the above steps 201 to 205, the first terminal is used as a carrier of the first SIM, and after data interaction with the background server is realized, data for deploying the target application program is sent to the first SIM through bluetooth connection, so that the first SIM generates the first key data.

In yet another optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

step 31, sending a request for sharing the car key service to a background server;

step 32, receiving a sharing link responded by the background server to the request feedback;

step 33, sending a sharing link to the second terminal;

step 34, receiving a request for applying for an authorization certificate sent by the background server, wherein the request for applying for the authorization certificate carries a second public key in second vehicle key data, and the second vehicle key data is generated by a second SIM in the second terminal based on the sharing link; the second vehicle key data comprises a second public key and a second private key which are mutually key pairs;

step 35, sending an authorization certificate to the first SIM under the condition of establishing Bluetooth connection with the first SIM;

step 36, receiving an authorization credential generated by the first SIM, wherein the authorization credential is an authorization credential signed by the first SIM using the first private key; the authorization certificate carries the second public key;

step 37, the signed authorization ticket is sent to the second SIM in the second terminal.

Through the above steps 31 to 37, based on the first terminal, the vehicle key service can be shared with the second SIM in the second terminal, so that the second SIM can also control the same vehicle.

In another optional implementation manner of the embodiment of the present application, after sending the signed authorization ticket to the second terminal, the method of the embodiment of the present application further includes: and sending a request for applying for canceling the car key service of the second terminal to the background server.

That is, after sharing the car key service with the second terminal, the car key service may also be revoked, and the specific revocation will be explained in detail below with respect to the second terminal and the second SIM side.

The method of the embodiment of the present application will be explained below from the perspective of a vehicle; referring to fig. 3, fig. 3 is a third schematic flowchart of a control method of a vehicle according to an embodiment of the present application. The control method of the vehicle shown in fig. 3 is performed by the vehicle.

As shown in fig. 3, the control method of the vehicle may include the steps of:

step 301, receiving a request for verifying identity information of a first SIM sent by the first SIM under the condition of establishing an NFC connection with the first SIM embedded in a first terminal;

step 302, sending random information to the first SIM under the condition that the identity information passes verification;

step 303, receiving signature information obtained by the first SIM signing the random information with the first private key;

step 304, verifying the signature information through the first public key, and sending feedback information to the first SIM after the verification is finished, wherein the feedback information is used for indicating that the unlocking of the vehicle is successful; the first private key and the first public key are keys which are a key pair in the first vehicle key data.

As can be seen from steps 301 to 304, in the case that the NFC connection is established with the first SIM embedded in the first terminal, after the vehicle and the first SIM complete verification through the first private key and the first public key, the unlocking control of the first SIM on the vehicle is implemented. That is to say, because the first SIM itself has the NFC function, it is not necessary to consider whether the operating system of the terminal is matched with the vehicle, and therefore, NFC communication can be achieved only by requiring the vehicle to also have the NFC function.

In an optional implementation manner of the embodiment of the present application, before establishing the NFC connection with the first SIM built in the first terminal, the method of the embodiment of the present application may further include: step 41, receiving a first public key sent by the first terminal through the background server.

Based on the first public key, the vehicle can verify the signature information signed by the first SIM through the first private key by using the first public key in the process of controlling the vehicle through the first SIM, and then unlocking control of the vehicle is realized.

In an optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

step 51, receiving a request for verifying identity information sent by a second SIM under the condition of establishing NFC with the second SIM built in a second terminal;

step 52, sending a request for applying an authorization certificate to the second SIM under the condition that the identity information is verified;

step 53, receiving an authorization certificate carrying a second public key fed back by the second SIM;

step 54, under the condition that the authorization certificate is determined not to be in the blacklist, verifying the authorization certificate by using the first public key;

step 55, under the condition that the verification is passed, storing the second public key and sending random information to the second SIM;

step 56, receiving signature information obtained by the second SIM signing the random information by using the second private key;

and step 57, verifying the signature information by using the second public key.

As can be seen from the foregoing steps 51 to 57, after the second SIM is in NFC connection with the vehicle, since the authorization credential is an authorization credential signed by the first SIM using the first private key, the vehicle can verify the authorization credential by using the first public key, and then the vehicle stores the second public key in the authorization credential, and subsequently verifies the signature information, which is sent by the second SIM and signed by using the second private key, by using the second public key, thereby implementing unlocking control of the second SIM on the vehicle.

In another optional implementation manner of the embodiment of the present application, the method steps of the embodiment of the present application may further include:

step 61, receiving a request for canceling the second terminal vehicle key service, which is sent by the first terminal through the background server;

and step 62, deleting the second public key in the second vehicle key data stored locally.

After the second SIM can control the vehicle, the first terminal may revoke the vehicle key service thereof so that the second SIM loses control over the vehicle, and in this process, the authorization credential needs to be added to the blacklist first, and the second public key of the second vehicle key data is deleted, so that the vehicle cannot verify the signature information signed by the second private key and sent by the second SIM, and then the control over the vehicle by the second SIM is revoked. Therefore, the control of other users on the vehicle can be conveniently carried out, the control of other users on the vehicle can be conveniently and quickly cancelled, the control effect on the vehicle is improved, and meanwhile the safety of the vehicle is guaranteed.

The present application will be explained from the perspective of the second terminal, and referring to fig. 4, fig. 4 is a fourth flowchart of a control method of a vehicle provided in an embodiment of the present application. The control method of the vehicle shown in fig. 4 is executed by the second terminal.

As shown in fig. 4, the control method of the vehicle may include the steps of:

step 401, receiving a sharing link which is sent by a first terminal through a background server and used for sharing a car key service;

step 402, sending a request for obtaining a car key service to a background server based on a sharing link;

step 403, receiving a notification for generating vehicle key data sent by the background server;

step 404, under the condition of establishing bluetooth connection with a second SIM built in a second terminal, sending a notification to the second SIM;

step 405, receiving a second public key in second vehicle key data generated by the second SIM in response to the notification;

step 406, sending a request for applying for an authorization credential to the first terminal through the background server, wherein the request carries the second public key; the second vehicle key data is the second public key and the second private key of the key pair of the second vehicle key data;

step 407, receiving a signed authorization certificate sent by the first terminal through the background server; and the signed authorization certificate is obtained by the first terminal through signing by the first private key, and the authorization certificate carries the second public key.

Through the steps 401 to 405, after receiving the sharing link which is sent by the first terminal through the background server and used for acquiring the car key data, the second terminal may notify the second SIM to generate the second car key data, and then the second SIM sends the second public key to the second terminal, the second terminal applies for the authorization credential to the first terminal through the background server, and after the first terminal signs the authority information and the second public key through the first private key, the second terminal receives the signed authorization credential, thereby completing the sharing process of the car key service, so that other subsequent users can control the car.

In another optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

step 71, receiving a deleting instruction which is sent by the background server and used for deleting the car key service;

and step 72, sending a deleting instruction for deleting the car key service to the second SIM under the condition that the Bluetooth connection is established with the second SIM.

Through the above steps 71 and 72, after the sharing of the car key service is completed, the cancellation of the car key service, that is, the cancellation of the control of the other users on the car, can also be realized.
